The age limit(or w.e you want to call it.) is going to skyrocket. With the amount of people there are in the world today, the amount of celebrities there are probably MILLIONS of people, who are of relevance, and have over 100,000+ fans, and there are more and more formed every month, theres no way ALL of them die within the next 90-110 years.
I predict that the world will either end in the next 100 years, or the life expectancy is going to increase, specifically those with wealth, who can afford to take care of themself to the best of there ability.
